APPARATUS FOR CURLING HAIR.

Application filed December 4, 1913.

T 0 all whom it may concern:

Be it known that I, Gnonen KREMER, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Apparatus for Curling Hair, or" which the following is a specification.

My invention consists of a new and improved form of an electric hair curling device, and is adapted particularly to curl and treat the roots of the hair.

it has been the fashion for a number of years with a large number of women to have their hair treated in such a way that it will be curled and stay permanently curled. This is done by taking a number of strands of hair and curling them around a metal hair curler, and then placing the curler with the hair curled around it in an electric tubuiar heater, approximately siX or eight inches long so that the hair is subjected to great heat for about twenty minutes and when taken out of the heater it is curled and remains permanently curled. Experience has shown that in the course of a month or wo, the hair will of course grow out and when it does so it leaves a space of approximately an inch or two inches which is then uncurled or in other words is substantially straight. Experience has demonstrated that if an attempt is made to curl this portion of the hair near the roots by subjecting the whole length 01' the strands of hair to the heating process again, the part which has been once curled is injured by the reheating and in many instances has been wholly destroyed.

It is the object of my invention to subject the roots or uncurled part of the hair near the head to the same process of curling and heating as has been previously done to the whole length of hair, without reheating that portion of the hair which is already curled. I accomplish this result by making the heater of approximately one inch in'depth or at the outside two inches, but preferably one inch.

In the accompanying drawing, Figure 1 is a side elevation of my device. Fig. 2 is a sectional view taken along the line 00 w of Fig. l.

The device consists essentially of a metal tapered tubular cylinder a providing a member having the heat oonductively character- Specification of Letters Patent.

Serial No. 804,654.

izing members formed of metal and having a bore of relatively great diameter compared with its length, said device having asbestos rims b and 0. Around the outer portion of the cylinder (4 between the rims is placed a mica insulator (Z, and on top of this insulator are wound German silver resistance wires 6. The ends of these wires 6 are connected to the terminals 7 and these terminals are embedded in an asbestos insulator 9' preferably rectangular in form which can also be utilized as a holder or handle. The inner portion of the spool on top of the resistance wire is provided with insulating material 7b which may consist of asbestos or any well known non-conducting substance. On top of this substance is located a frustoconical metal shield i constituting an outer tubular member with a winding of asbestos cord 7' wrapped about the same. An inner portion of the rear rim or wall 7) is reduced to form an annular shoulder Z) to receive the outer tube or shield i which abuts the rear wall.

As has been previously stated the heater has its tubular bore wider at the mouth than at the outlet in order to allow easy ingress of the hair into the mouth of the heater.

I claim: 7

1. A heater for curling the newly grown portions of hair previously curled without reheating the old hair, comprising a short spool having a core made of heat conducting material with an uninterrupted bore from end to end through which the hair to be treated is entirely passed until only the new growth of hair is contained therein, and a resistance coil closely embracing said core.

2. A heater for curling the newly grown portions of hair previously curled without reheating the old hair, comprising a short spool having a core made of heat conducting material with an uninterrupted bore from end to end through which the hair to be treated is entirely passed until only the new growth of hair is contained therein, a resistance coil closely embracing said core, and an insulating handle attached to the outer end of the spool through which the conducting wires pass to the resistance coil.

3. A heater for curling the newly grown portions of hair previously curled without reheating the old hair, comprising a short spool with heat insulating ends, and a tubular core of heat conducting material that is adapted to be slipped over the portion of hair to be treated until only the new growth of hair is contained within the bore, a resistance coil closely embracing said core, insulating material applied over said coil, and. a shield placed about the insulating material.

4. A heater for curling the newly grown portions of hair previously curled without reheating the old hair, comprising av short spool of a length no greater than that of the new hair to be curled with a tubular core of heat conducting material having insulating ends and adapted to be slipped over the hair to be treated until only the new growth of hair is contained therein, a resistance coil wound closely around said core between its ends, insulating material surrounding the coil. a shield over the insulating material, and an insulated handle projecting from one end of the spool, through which handle the conducting wires pass to the resistance coil.

5. A heater for curling the newly grown portions of hair previously curled without reheating the old hair, comprising a short spool of a length no greater than that of the length of the new hair to be curled with a tapering tubular coil of heat conducting material wider at the mouth or end that lies against the head to permit easy insertion of the hair and with heat insulating ends, a resistance core wound around said core between its ends, a sheet of insulating material between the coil and the core, insulating material surrounding the resistance coil, a metal shield over the insulating material, and a handle formed of insulating material rigidly attached to one of the spool heads through which handle the conducting wires pass to the resistance coil.

6. A device of the class described, comprising an open ended tubular member of relatively highheat conductivity having a bore of relatively great diameter compared with its length and adapted to contain a portion of a coil of hair intermediate. its ends and permit other portions to extend beyond opposite ends thereof, an outer tubular member and a heating means disposed between said members andv fillingthe space between the'inner andouter tubular members whereby a high degree of heat may be concentrated to heat the portion of the.

coiled hair adjacent the head.

7. A device of the class described, comprising an open ended tubular member possessing heat conductivity andadapted to surround a portion of a coil of hair adjacent the persons head and permit other portions to extend beyond opposite ends thereof, a heating means surrounding said tubular member and a sheet of insulating material disposed between the heating means and said tubular member.

8. A device for treating the portion ofa coil of a persons hair adjacent the head without affecting the remaining portion of the coil, said device c mprising an inner tubular member adapted to contain the said portion of hair and to permit the other portion to extend therefrom, an outer tubular member being frusto-conical with the smaller end designed to form a joint to fit adjacent or near to the persons head, a heating coil disposed between said tubular members close to the joint, so that the hair can be waved as close to the head as possible.

9. A device of the class described, comprising a rear wall in the form of a circular disk forming a support for the device at the rear end of the same and having an opening therethrough, a short metal tube open at both ends and having one end inserted through the opening in said wall and fastened to the wall, the inner portion of said rear wall being reduced to form an annular shoulder, an outer tube having one end inclosing said shoulder, abutting against said rear wall and spaced from said inner tube, a front disk between said tubes, an electric heating means disposed between said tubes and in advance of said rear wall, electric leads passing through said rear wall from its outer face and connected to said heating means and a handle rigidly connected to said rear wall and ofi'set from the opening through said wall and from the bore of said inner tube, said device in advance of said rear wall being free of pro jections whereby the device may be inserted into a mass of hair without entangling the same.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
